????? essential models of accidental topos of projective line .... ???....

"pair of N-sets, equipped with [-1]-twisted isomorphism between their tensor products with Z" ... ???

"remember just the first N-set" .... ???.... ??left adjoint??? ...??? ...(also right adjoint ....???....) .... ???? ....???....

???take the other N-set to be the tensor product of the given one with Z ... ???maybe that's the right adjoint?? ... ???and there's no left adjoint ???? .... ????? .....

??no essential models in this example as maybe fitting with ... ???categorified intersection of basic toric opens as essential operation .... ???? .....

???removing unique essential model ... ???? .... whether new essential model ever arises from among previsouly un-essential remainder ... ??? ....

???vague resemblance between "essential model" and "coherent object" ??? .... ??superman example of "basis" ... ????...... ???? .....
